Using New Accounts to Spam Comments on YT

Do you think a lot of accounts are getting banned from Youtube because the comments are coming from accounts that's new with none of them having videos?

Would it be better to post comments and favorites from already established accounts that look as if there active with videos being posted?

I just feel if someone clicks on the user name on the comment they would see these accounts are just for spamming. Tell me what you guys think.

yea I'm always try working with accounts add friends on them comment other videos subscribe to other feeds also posting some videos on them. I think it's better that way.
